2 Claims.

This invention relates to improvements in resilient padding for thefacing of ironing boards, pressing machine bucks and rolls, and forother purposes in connection with which a resilient padding material isrequired.

This invention has for an object to provide a novel construction ofpadding for the purposes stated which is characterized by a high degreeof resilient conformability to various degrees of pressure exertedthereon by material supported thereby while undergoing pressing or otheroperations, or by reason of irregularities in the shape or surfacecontours of the supported material, while at the same time providing aninterstitial or porous pad mass of substantial density and thus adaptedto support and efficiently sustain the material being pressed inopposition to pressure applied thereto.

The invention has for another object to pro- 2 vide a novel constructionof fabricated padding material of such density as is well adapted towithstand, without break down, the repeated blows and pressures to whichit is normally subjected in use; while at the same time being adapt- 25ed, by reason of the structural characteristics of the material of whichit is made, to provide, in addition to the requisite resiliency as awhole, a certain degree of give and take interplay or movement betweenelements thereof, whereby 30 the padding will quickly, easily and snuglyconform itself to protuberances on the material supported thereby, whilenevertheless presenting such material smoothly spread and substantiallyuniformly supported subject to such'operations or effects as may bedesired to be administered thereto.

To attain the above stated objects, the novel paddin according to thisinvention-is formed by convolved or spirally curled metallic strands ofcomparatively small diameter laid in contiguous parallel relation toform layers thereof, and with a multiplicity of such layers superposedone upon another until a required thickness of packing body is attained.The convolved or spirally curled metallic strand may be disposed on andalong a central flexible carrier core or not, as is desired in any givencase. Due to the inherent springy or elastic lateral compressibility ofthe convolutions or coils, as well as to interplay between theconvolutions or coils of adjacent strands, there is permitted a localresilient compressibility or play at those portions of the area of thepadding body which may be engaged by pretuberances on the materialsupported thereby 5 subject to a pressing or other action, so that saidprotuberances will readily and snugly imbed themselves in the padding,while otherwise the material will be smoothly supported and adequatelyhacked to receive the efiects of said pressing or other action.

Other objects of this invention, not at this time more particularlyenumerated, will be understood from the following detailed descriptionof the same.

Illustrative embodiments of padding according to this invention areshown in the accompanying drawings, in which:

Fig. l is a fragmentary plan view of the novel padding material asapplied to an ironing board, pressing machine buck, roll or othersupport, as the case may be, a portion of the facingcover therefor beingbroken away to disclose the padding mass; Fig. 2 is a transversesectional, view of the same; and Fig. 3 is a fragmentary longitudinalside elevation and part longitudinal section, showing the application ofmaterial thereto for pressing, and also showing how a protuber ance onsaid latter material will imbed itself in the padding under pressure.

Fig. l is in part a side elevation and in part a longitudinal section,and Fig. 5 is a plan view with parts broken away, these viewsillustrating how the novel padding will accommodate itself to odd andirregular shaped bases. Fig. 6 is a view similar to Fig. 5, but showinganother shape of base.

Figs. '7, 8, 9, 10 and 11 are various schematic views illustrating onemethod of assembling and fabricating the convolved or spirally curledstrand in making up the ultimate novel padding according to thisinvention; and Figs. 12 and 13 are fragmentary sectional views showingvarious forms of stitching which may be employed to retain the assembledstrands in padding forming relation.

Fig. 14 is a fragmentary view of the convolved or spirally curled strandmade of round wire and provided with a central carrier core; and Fig. 15is a similar view showing the strand made of flat or ribbon-like wireand provided with a central carrier core.

Figs. 16 and 17 are respectively fragmentary views of the convolved orspirally curled strand without a central carrier core, one being made ofround wire and the other of flat or ribbon like wire.

Similar characters of reference are employed inthe above describedviews, to indicate corresponding parts. V

In making up the novel padding of this invention, it is preferred toemploy a strand A composed of a central carrier core l upon, along' andabout which is comparatively closely convolved or gimped a spirallycurled metallic wire having inherent springiness, the coils of which areof small diameter to assure attainment of a pad body mass which is ofsubstantial density and yet resilient; the metallic wire may be eitherof round cross-sectional shape, as the wire H (see Fig. 15), or the samemay be of flat or ribbon-like form, as the wire [2 (see Fig. 15), or infact the wire may be of any other suitable or desired cross-sectionalshape. The carrier Core i0 may be made of cord, fibre, metallic wire, orother suitable but flexible material. While it is preferred to use thespirally curled metallic wire in gimped or convolved relation to acentral carrier core, as above described, this is not absolutelyessential, since the strand A may consist in the convolved or spirallycurled wire alone, i. e. without the carrier core, as e. g. the spirallycurled round wire [3 (see Fig. 16) or the spirally curled fiat orribbon-like wire I4 (see Fig. 17), or of a spirally curled wire of othersuitable cross-sectional shape.

Illustrative of one method which may be used to fabricate the strand Ainto a desired padding body mass, reference may be had to Figs. 9 to 11inclusive, wherein is shown a form or frame l5 having laterally spacedlegs l6. This form or frame is preferably made of heavy rigid wire orrod-like material and is of a width and length more or less incorrespondence to the dimensions of padding body desired to be produced(see Fig. 7). The padding body is built up upon this form or frame I 5by winding the strand A transversely around the same from end to end,with the turns closely placed or contiguous (see Fig. 8). When onewinding from end to end of the form or frame I5 is completed, a secondand subsequent end to end windings are made, thus forming superposedlayers of such windings, until a desired thickness of padding body isfinally attained (this is shown in Fig. 9, wherein successive outerlayers thus obtained are broken away in part to disclose underlyinglayers).

When a body of suitable size and thickness, has thus been built up onthe form or frame IS, the layers of wound strand A are engaged by meansdesigned to hold or secure the same in their body forming relation andagainst unwinding, unraveling or other disintegration or displacement.One and a preferred method of attaining this end is to sew through theformed body, transversely of the windings of strands A, suitablydisposed and spaced runs of stitching B, which pass through the body.The stitching may be made with a textile thread or cord, or with wire orother suitable material; and the form of the stitching may be more orless varied, two specific and illustrative forms thereof being shownrespectively in Figs. 12 and 13.

After the padding body has been completed by application thereto of theholding stitching B, the form or frame 15 may be withdrawn therefrom, bysliding the legs I6 of the same outwardly from an end thereof, as e. g.in the direction of the arrow :2 applied in Fig. 10. It is notessential, however, to remove the form or frame [5, and, if desired,especially in connection with padding bodies of irregular peripheralshapes, the same may be allowed to remain in the body interior, to serveas a means for retaining the desired peripheral shape thereof.

Upon completion of the padding body, the same is mounted on a desiredsupport H, which may be an ironing board, a pressing machine buck, amangle roll, or such other foundation as is provided, in any given case,for the support of material to be subjected to a pressing or otherdesired action or treatment. Over the padding body, thus mounted, isarranged and suitably secured a facing cover E8. The facing cover I8 isusually made of a suitable textile fabric, or it may be made of othersufiiciently flexible sheet material.

In the form of the fabricated padding body described, the windings ofstrands A lie, both horizontally and vertically, closely contiguous oneto another, so that the coils thereof will mutually bear more or lessone upon another, whereby a comparatively dense pad mass, whichnevertheless possesses a very lively resilient effect, is attained whichvariably yields to pressures applied thereto and yet quickly reacts toan expanded normal condition when pressure thereupon is relaxed, andwhich, as a whole, provides sufficient density to well sustain materialbeing pressed in opposition to applied pressure. At the same time moreor less mutual interplay or movement between adjacent coils may occur,especially at local areas which are subjected to pressure in excess ofthat applied to surrounding areas. As a consequence of the resiliencyand interplay or relative movement of the coils, the padding body tendsto quickly yield to and closely and snugly conform itself toprotuberances which may project from material spread and supportedthereon subject to a pressing action or operation. For example, a buttonl9 projecting from the material being pressed (see Fig. 3) will easilydepress and sink into the padding body mass, so that the latter willclosely and snugly conform to the button in such manner as not tointerfere with but rather assure the smooth lying of the material 20surrounding the button, especially the areas of the latter closelyadjacent to the button.

While a method of fabricating the padding body has been describedwhereby the strands A are disposed as contiguous side by side windingsarranged to form superposed layers, it will be obvious that within thebroad aspects of this invention, other dispositional arrangements of thestrands A and the coils thereof may be utilized.

It will also be understood that the padding body fabricated from thestrands A may be made of various peripheral shapes to suit specificdesires or requirements in connection with the use thereof. In Figs. 4to 6 inclusive examples of irregular padding body shapes are shown.

It is desired to also point out that the novel padding is adapted forspecific uses other than as a support for material to be subjected to apressing action or operation. For example, the padding body is alsoadapted for use in furniture and like upholstery work, as well as forother purposes in connection with which a conformable and efficientlyresilient padding material is required.

Since various changes could be made with respect to the finished paddingand its detail make up, and many widely different embodiments of thisinvention could be made without departing from the scope thereof asdefined in the herefollowing claims; it is intended that all mattercontained in the above description or shown in the accompanying drawingsshall be interpreted as illustrative and not in a limiting sense.

I claim:

are of small diameter, disposed upon and along a central flexiblecarrier core, said strands being laid in contiguous side by siderelation to form a layer, a multiplicity of said layers being superposedto form a yieldable pad mass of substantial thickness and density,wherein said carrier cores serve to retain spiral coils of contiguousstrands against substantial relative displacement, and retainingstitching extending through the superposed layers and transversely ofthe'strands 10 composing the same.
